Configuring N Port Virtualization

NPV Mode

A switch is in NPV mode after a user has enabled NPV and the switch has successfully rebooted. NPV mode
applies to an entire switch. All end devices connected to a switch that is in NPV mode must log in as an N
port to use this feature (loop-attached devices are not supported). All links from the edge switches (in NPV
mode) to the NPV core switches are established as NP ports (not E ports), which are used for typical interswitch
links. NPIV is used by the switches in NPV mode to log in to multiple end devices that share a link to the
NPV core switch.
Note In-order data delivery is not required in NPV mode because the exchange between two end devices always
takes the same uplink to the core from the NPV device. For traffic beyond the NPV device, core switches will
enforce in-order delivery if needed and/or configured.
After entering NPV mode, only the following commands are available:
